5.2 Fair

Jul 2017

KAYAK

Pros:

Price was fair and they upgraded us when they ran out of the class of car I rented.

Cons:

The rep asked for a 2nd phone number, home, spouse, parent etc, when I asked why, since I have never had any car company require a 2nd number, including enterprise, which I had just used the week prior, she stated that it was company policy and they can't rent to me without a 2nd number on file and that they wouldn't sell my info to outside companies. They only use the info to get a hold of me if they can not reach me on my cell do to lose or damage to my phone. What sense does that make? If my cell is lost or stolen, how will anyone be able to reach me? If I gave her my home number (which I do not have), and I am gone, who is suppose to answer and get a hold of me if no one is home, LOL. Her logic was so off. My biggest complaint about this policy is, why is a car company being so nosey? No one needs my mother or other family members phone numbers. I am 43 years old, I think I can handle my own car rental without someone else's phone number having to get involved. To top it off I had to wait 30 minutes for a car to be cleaned and it wasn't even very clean when we got it.

my rental was NOT clean, smelled like pot. We complained but only one employee was there and told us the hose was broke and the toilet was out of order. Joseph said she tried to remove the smell but the smoke had imbedded the fabric.

8.0 Very good

Jan 2021

KAYAK

Pros:

The pickup was great. The O'Fallon branch was super helpful friendly and efficient.

Cons:

The williamsburg office is closed. Like until further noticed closed. I tried to call the number left on the door and there was no answer or option to speak to someone. I am still hoping I am going to be getting my 200$ hold back. I left the keys in the box like instructed but not sure how they will know.

Pros:

Terrible customer service. Did not add my AAA discount. Will not adjust since they closed it out.

Cons:

Best customer service. I had to call and ask for a receipt 3 times to get a simple email. Agent told me she would add AAA discount at the counter but never did and not told they could not adjust. Terrible way to let a customer down

Pros:

Cons:

No washer fluid. I drove 40 miles to pickup the van n it wasn't there. I had to drive back home bccthey didn't know when it would be there n drive all the way back 3 hours later. Not cool the day before a trip when I had things to do.

8.0 Very good

Oct 2017

KAYAK

Pros:

Vehicle got good gas mileage and was comfortable.

Cons:

Whatever Hertz uses to "clean" (wipe down surfaces inside the vehicle) the vehicles stinks! To me, it smells like what schools use to spray on an area after a student vomits. (former teacher) The person who did the walk around asked, "What? You don't like that?" I aired out the car in our garage for 24 hours before I could get in and drive it with windows shut.

6.4 Okay

Jul 2017

KAYAK

Pros:

I rented a Nissan Versa and overall, it handled well. It had enough power for Colorado passes, but just barely. Roomy enough for two suitcases two backpacks and assorted camping gear.

Cons:

Ten miles down the road the seal on the windshield began to flap in the wind; I repaired it myself. Also, the inside of the front windshield appeared to be wiped down with a soapy cloth and left to dry. I was told I could add an extra driver later in the trip, which I did, but wasn't told that doing so incurred an extra $13.50 per day fee. By that time I was nearly 400 miles into the trip (the fee was reduced with the use of my AAA card), but it was something that should have been mentioned during the initial pickup.

We rented a minivan. Unfortunately when we got there, they claimed they had too many minivan rentals and did not have one available. Instead they wanted us to wait 3 hours or take a 12 passenger van. We had to cancel our rental and pay double somewhere else. The customer service agent was unprofessional and said it was not their responsibility to call us to let us know what we had reserved would not be available.
